It should be noted that, in the situation that not conflicting, embodiment and the feature in embodiment in the present invention can combine mutually.Below in conjunction with accompanying drawing, each preferred embodiment of the present invention is described further.
Refer to Fig. 1 and Fig. 2, the figure shows the structure of the cable drum that the embodiment of the present invention provides.This cable drum comprises:
Reel shell 9, and be arranged at scroll spring 2 and the planetary gear speed reducing mechanism 8 in this reel shell 9;
The input of planetary gear speed reducing mechanism 8 is connected with reel shell 9, and output is connected with the free end of described scroll spring 2.
The cable drum that the present embodiment provides is spring-driven, and the difference of itself and existing cable drum is, it is provided with planetary gear speed reducing mechanism 8, i.e. the rotation of reel shell 9 passes to scroll spring 2 by planetary gear speed reducing mechanism 8.The effect that planetary gear speed reducing mechanism 8 is set is, the rotation of reel shell 9 is slowed down, and rotates under the prerequisite of same number of turns thus at reel shell 9, reduces scroll spring 2 pretension length, reduces the required coiling length of scroll spring 2.Particularly, this cable drum comprises: reel shell 9, and this reel shell 9 is for being wound around cable rope, and its periphery can be provided with cable trough 91; Scroll spring 2 and planetary gear speed reducing mechanism 8, all be arranged in reel shell 9, scroll spring 2 is provided with stiff end and free end, and position fixed ends are fixed, free end is connected with the output of planetary gear speed reducing mechanism 8, and the input of planetary gear speed reducing mechanism 8 is connected with cable drum 9.
Above-mentioned planetary gear speed reducing mechanism can be one-level planetary gear speed reducing mechanism, also can adopt planetary gear speed reducing mechanism reaching or above grade two according to the requirement of step-down ratio.The structure of one-level planetary gear speed reducing mechanism is comparatively simple, take one-level planetary gear speed reducing mechanism as example, and it specifically can comprise:
Sun gear 4, it is connected with reel shell 9, and with reel shell 9 coaxial rotation;
Planetary gear 1, with sun gear 4 external toothings;
Ring gear 5, itself and planetary gear 1 external toothing; This ring gear 5 is connected with the free end of scroll spring 2.
The sun gear 4 of this planetary gear speed reducing mechanism forms above-mentioned input.Sun gear 4 can be fixed on the bearing of reel shell 9, and sun gear 4 coaxially arranges with reel shell 9.Ring gear 5 forms above-mentioned output, and it is connected with scroll spring 2.For the ease of connecting, the bottom of this ring gear 5 is preferably provided with mounting panel 51, and the free end of scroll spring 2 is fixed on this mounting panel 51.The free end of scroll spring 2 can be arranged in mounting panel 51, also can be fixed on mounting panel 51 by securing members such as screw, steady pins.
Further, for the ease of fixing and supporting above-mentioned planetary gear speed reducing mechanism, the cable drum that the present embodiment provides can also comprise mount pad 7, and this mount pad 7 is provided with axis 3, and the sun gear 4 of planetary gear speed reducing mechanism is sheathed on outside this axis 3.In addition, planetary gear 1 can be installed on planet carrier, and planet carrier also can be installed on above-mentioned mount pad 7.Similarly, for the ease of the position of fixed scroll spring 2, this cable drum can also comprise spring fitting box 6, and scroll spring 2 is arranged in this spring fitting box 6, this spring fitting box 6 can be fixed on above-mentioned mount pad 7, and the stiff end of scroll spring 2 is fixed on this spring fitting box 6.
In order to prevent in rotation process, between sun gear 4 and mounting panel 51, there is fretting wear, between above-mentioned mounting panel 51 and sun gear 4, can be provided with clutch shaft bearing 81, it will be appreciated by persons skilled in the art that this clutch shaft bearing 81 should be installed on the part that sun gear 4 does not arrange external tooth.Similarly, in order to prevent between mounting panel 51 and spring fitting box 6, fretting wear occurring in rotation process, between above-mentioned mounting panel 51 and spring fitting box 6, can be provided with the second bearing 82.Above-mentioned two bearings play the effect that prevents the excessive friction of parts generation in relative rotation.Those skilled in the art can select two bearings to arrange according to the installing space of parts simultaneously, also can only arrange one.
In the cable drum that above-described embodiment provides, by selecting the planetary gear speed reducing mechanism of different drive ratios, can realize different reel shell 9 rotational travel and scroll spring 2 pretension Length Ratios.It will be understood by those skilled in the art that, the gearratio of planetary gear speed reducing mechanism is larger, reel shell 9 rotational travel and scroll spring 2 pretension Length Ratios are also larger, and the required coiling length of scroll spring 2 is also relatively little, and now the structure of epicyclic transmission mechanism is also relatively more complicated.Consider the coiling length of existing single scroll spring 2, and the conventional length (100 meters of left and right) that is wound in the cable rope of reel shell 9, it is (2～8) that the embodiment of the present invention preferably adopts gearratio: 1 planetary mechanism, this kind of gearratio adopts one-level planetary mechanism just can realize, simple in structure, workable.。
The operation principle of the cable drum that the present embodiment provides is as follows:
During electric discharge hawser, cable rope band movable reel shell 9 rotates; Reel shell 9 drives sun gear 4 to rotate, and by engagement, sun gear 4 drives planetary gear 1 to rotate; By engagement, planetary gear 1 drives ring gear 5 to rotate; Ring gear 5 rotates and drives mounting panel 51 to rotate, and mounting panel 51 pulls the free end of scroll spring 2 to stretch out, and scroll spring 2 is by pretension thus.
The cable drum that adopts above-described embodiment to provide, can meet the folding and unfolding of the cable rope of length, cable rope can four layers or five stacked adding be wound in reel shell 9, so cable trough 91 degree of depth of reel shell 9 are preferably not less than five times of electric cable diameter.Due to above-mentioned cable drum, can meet equally the folding and unfolding of the cable rope of length, in this cable drum, a scroll spring 2 can be only set.This scroll spring 2 can be plane scroll spring, can be also valute spring.
As shown in the above, the cable drum that the embodiment of the present invention provides comprises reel shell, scroll spring and planetary gear speed reducing mechanism.Wherein, the input of planetary gear speed reducing mechanism is connected with reel shell, and output is connected with scroll spring, and the rotation of reel shell passes to scroll spring by planetary gear speed reducing mechanism, can rotate under the prerequisite of same number of turns at reel shell thus, reduce the required coiling length of scroll spring.With respect to prior art, the cable drum that the embodiment of the present invention provides can reduce the quantity of scroll spring when guaranteeing cable rope coiling length, further, by suitable gearratio is set, a scroll spring can be only set.With respect to scroll spring, the weight of planetary gear speed reducing mechanism is lighter, small volume, and cost is also cheaper, makes thus whole cable drum also have advantages of that cost is low, lightweight and volume is little accordingly.
The embodiment of the present invention also provides a kind of engineering machinery, be preferably crane, this project machinery is provided with above-mentioned any cable drum, because above-mentioned any cable drum has above-mentioned technique effect, therefore, the engineering machinery that is provided with this cable drum also should possess corresponding technique effect, and its specific implementation process is similar to the above embodiments, does not hereby repeat.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
